The present disclosure relates to a method of flocculation, wherein harmful cyanobacteria are flocculated via metal-organic framework, and wherein the metal-organic framework comprises chromium, which is environmentally friendly. Water-stable Cr(III)-based MOFs, structured as NH.sub.2-MIL-101, remove harmful algal blooms, such as Microcystis aeruginosa, from natural water sources by promoting flocculation. NH.sub.2-MIL-101(Cr) MOFs efficiently remove harmful algae from water without creating secondary pollution and without causing the harmful algae to release intracellular toxins.

Methods of synthesizing transition metal dichalcogenide nanoparticles include forming a metal-amine complex, combining the metal-amine complex with a chalcogen source in at least one solvent to form a solution, heating the solution to a first temperature for a first period of time, and heating the solution to a second temperature that is higher than the first temperature for a second period of time.
